Lex has a set of four cubes, each with a letter on each of its six faces. Each of the 24 faces is different.
Lex was playing with these cubes the other day and formed the following 16 words:
OPEN OWNS TERN FEUD
GAUD PAUL DAZE AVOW
IAMB XYST BUND CUKE
DEFY RICE HOPS SHUT
Identify the letters found on each cube; the order of the cubes doesn't matter.
